Quantum Field Theory C (Physics 215C)
Spring 2015
Lectures:
TTh 11:00-12:30 in Meyer Hall 5301.
Lecturer: John McGreevy
Mayer Hall 5222; email: mcgreevy at physics.ucsd.edu
Office Hours: Thursdays 2:30-3:55pm, or by appointment.
Use of the Web:
The course web page is
http://physics.ucsd.edu/∼mcgreevy/s15/.
Problem sets, solutions, lecture notes, handouts, announcements, etc will be distributed via
this page. You should check it regularly (e.g. before each lecture) for new material. It will
help to look at the relevant lecture notes before the lecture happens.
Content:
Here’s my opening bid: Theory of renormalization, effective field theory, effects of topology
in QFT, anomalies, solitons and defects, lattice models of QFT, CFT in d = 1 + 1 and in
d > 1 + 1. The choice of subject matter will evolve in response to the needs of the class
membership.
Texts:
I do not plan to follow any textbook very closely. My posted lecture notes will be the main
text. The textbook by Zee is wonderful and you should all keep it by your bedside. I will
attempt to refer you to some relevant sections of the following books, most of which have
been placed on reserve at S&E Library (or are available electronically):
Quantum Field Theory in a Nutshell, by Anthony Zee.
Quantum Field Theory of Many-Body Systems, by Xiao-Gang Wen.
Aspects of Symmetry, by Sidney Coleman.
Gauge Fields and Strings, by Alexander Polyakov.
Field Theories of Condensed Matter Systems, by Eduardo Fradkin.
The Physics of Quantum Fields, by Mike Stone.
Grading:
Grades will be determined by problem sets, class participation, and a brief final paper.
Problem sets:
Problem sets are a very important part of this course. Sitting down yourself and trying
to reason your way through a problem not only helps you learn the material deeply, but
also develops analytical tools fundamental to a successful career in science. I recognize that
students also learn a great deal from talking to and working with each other. I encourage
each student to make his/her own attempt on every problem and then, having done so, to
discuss the problems with one another and collaborate on understanding them more fully.
Such collaboration adds most to the understanding of those participants who have done the
most by themselves first. The solutions you write up after any discussion and then submit
must reflect your own work. They must not be transcriptions or reproductions of other
people’s work.
In doing the problems, you should feel free to use whatever computational software (e.g.
Mathematica) you find useful; please make a note in your write-up when you do so.
Problem sets will be posted on the course web page
http://physics.ucsd.edu/∼mcgreevy/s15/hw.html .
They will generally be due at the beginning of lecture on Tuesdays.
Miscellaneous unsolicited advice about how to do well in this class:
Come to lecture! I will post my lecture notes, but they are intended as a supplement to
what is presented in lecture, not a substitute.
Keep up with the material. Review the lecture notes from previous lectures before the next
one. The structure of this course is a bit of an experiment, and I am relying on all
of you to follow its twists and turns. I will post the relevant reading assignments in
advance; read ahead.
Start the homework problems as early as possible. Give yourself some time to think about
them, and keep them in mind when you are reading and in lecture.
Ask lots of questions: in lecture, in office hours, in discussion section. The fact that you
can ask questions is the point of having classes and not just having everyone go learn
on their own.
